I did not expect me doing this, but I would appreciate some non bias suggestions (I know it might be hard since this is an omv subreddit, but try).

I am running unraid today, with a 12th gen intel server with 2x sas cards, in total of 10X 10TB drives (will be expanded in the future), 4x 8TB U.2 Drives and 4x 2TB NVME (all enterprise class drives). Today the U.2 drives are used as cache in unraid in front of the "slow" regular harddrives.

I am not a beginner in infrastructure, but unraid has served me well. I have some issues though and that is the lack of flexibility of for example docker, where if I want to run compose its fully unsupported and using slackware means that a lot of monitor tools are hard to get running cause of the non standard systemd.

I tried truenas scale, and I do not want to run k8s on everything. OMV looks for me to be a good comprimise, where you in reality run debian with a good UI on top so that the distro is available to do what I want. So this is the question; how would you suggest me migrating from unraid to OMV and keep a high speed drive system knowing I have 4x fast drives and 10X slow drives, or do you guys think I should stick with unraid?

To info I am trying the v7 or OMV so the testing one. From what I understood that is going to be released soon?
